Theishaft 1, tothe end'of which geni-wheel 2 is fixed, 'cxtends'throgli thcipinon iaandth ineasnri'ng-whecl A at itsl centre, and is kept therein by the end of arm a, which"passcshrough aholein th end of the shaft-1. This shaft has a shoulder turned upon it, which rests agaistthe projecting endcf Pinie at. E is an eccentric shipping-plate, piroted en or at the base of the {ixd shaft 2', on which therlong spe: wheel 3 works. The hippingplateE servec as the bascfor the adjustable" uiechaniisiin, by which thc instrumct `may he readily adapted to measure the superficies of the different 4lengths of 'lnmher or other matriels. Th mechanism consists of, the frame F, which is secured by screwsito thcfpla'tdE, and 4t e seriesoi diffcrentlsizc pinions 4,5, 6, 7, 8, 9, forming a cone of pinions, `workinsg'on `the `f.=lni.i`t `10,l which i fastened,`liile fraincF, I plete E. `.Zit the apex of the inverted cone of pinions, and onthe' same "shaft, ,there is a large igearwhcel, 1 which` airways Vctainsits nicsh with the long spur-wheel 3. l The shaft or stud`2, upon Whiclithe spuiwlieel works, is ixednpcn' the base-plate C, and exlteiids through the eccentric' plate E, andserics as n.1pi`voot-onwhic `the plate E moves in shipping the gearing. An adjustable bracket or yoke, G, hasiw perfratedarm, throng thepcroration.; of which the shaft 10 passes, and a third arm,`K, cittcnding between` the side pieces of fijan thrughiwhich the adjusting-screw H Aiorks, and as the two arms ofitlie yole upon shaft lilfenihraceztl cone of gears, together with the larger gear 11, they may all he adjusted andide'wn onshaft`-l`f-l` nieans' thescrew H, which. extends down t'nroizgh thc cap-piece I et' frame F. The inilled head J is inadc separatefro the screw H, and is recessed so as `te i'tnpon its upper end; and inl crdeitoadhere with sufiicient friction" thc @1rd of the screw H the latter is hifurcated, seins to cause" the branches tof serifcas springsjiressingen wardly against the recessed cap J, `and thereby produce suiicient friction `te` canse `the screw I-I to rcvolife'l reifoli'ing the milled head J, te adjust the `gearing embraced in the liracketior `yoke G', Bythisuieans offco `necting thc'millcd head withthc adjusting screw the liahilityct' `breaking the mechanism adjnstedisayoide when it arrivcs'at either termination of its adjustment. The eccentric" platc'E may be turnedupon.` i'tlspivot the base of' stud 2 by means of its handle 12, which will cause the in`e`clianisi1i` consistingof thcfr ine a1 yoke G, with the series of gears 4, 5, 6,7, 9, and 1l, to be inoved with itaround thelengfsnur-wheel3, ai 'mit of Contact with the transmitting `g;ear-wheel, und whilethc eccentric yipleteiifi, held` in that position theta ei :gears may he `adjusted up or downiugon their' shaft, as has been described; and when 'so held, the eciell eci of the projecting arm K of yoke G wili be brought in apposition iiitli'tlieslot in the drum L, whichslet h the 1i 16, 18, and 22 markedntits margins.

When the yo mtl; its gearing, is adjusted, so as to bring the endfof the arm K in line with the ligure 12 on the scale, the

centric shipping-plate E will be allowedte return' to its normal condition, so far as thearm K will permit; le arm K in the mean time will rest against the upper shoulder e of the notched segmental plate N.) And measuring the quantity of square feet ot' lumber of different lengths., the gearing actuatedl by the set-screw will be adjusted, as has been described above, to bring the different pinions d, 5, 6, 7, 8, and 9-into mesh with insmitting gear 2. The gear 2,' as ivill be secn,'reinains lixcegn respect to the movable :eccentric plato-and gearing, as a slot in the eccntric plate E is formed around the shaft l. of that gear, as represented in black ies in iig. (l. A retraevlng-spring, 14, seen in`dotted lines' in Iig. (l, serves to bring the eccentric plate E back its proper position when released from tho hand of the operator or person using the instrument, as herein ceified, The spring 14 is fastened by the rivet -n on the inner face of base-plate C, and nets against a detent tending through a slot in the basc-platc, the deten't being connected with the under side of the eccentric plate Screwed fast to the handle P tbereis a thumb-spring, m, which, whenldepresscd,.will raise the brake-spring which is secured by screws to the rim D. The dotcnt or brake q, represented in dotted lines in fig. 6, bears `einst the periphery of the wheel A, to retain the wheel when the instrument is not in actual use; but by pressing the thumb-springt, the spring?, with 'its brake Il, will be raised from contactwith wheel A, which ll be necessary while the wheel A is being revolved upon the surface of' the materials being measured. `liotches .serrations may be formed -in the periphery or flange ofdfwheel A, into which `the detcnlt would enter to retain J wheel A in a xed position. The arm a, seen in fig. 5, occupies the groove i', in the small central disk s, g.' 3, ,and to the dish e the hand t is screwed, and the two'revolve together. The screw u passesv through the ntre of dial-plate B. Disk s is provided with arm t', 'which at each revolution 'ofv hand t, strikes onev of the ns w of the disk or rotary dial R, and causes it to move around o netenth of a revolution; a d when dial R 's made anentire revolution, its arm z will strike one of' the ten pins, y, of rotary dial T, causing it to move ound one-tenth'of. a revolution, and these movements are in like mannercommunicated -to disks or dials I I. will therefore be seen that ten revolutions ot' disk s andthe pointeriiand t will give one revolution to dial and ten revolutions of dial .R give one revolution to dial T; ten revolutions of dial T give one revolution dial I", and ten revolutions of dial If give one revolution to dial I.. vThese lfour revolving dials are secured on studs, connected with the innerside otfdial-plate E. lhev revolving dials nrechainbered, to vreceive a iral spring around each of their studs, and a pin through the end of each stud retains the spring, together th the dia. i,rw i th sulcient degree of pressure upon the inner facelof dial B, so as to prevent the rotating aisfrom moving upon their axes, except as they are propelled by the arms v, e, 17, and 18. The holes o in e face of dial Bare ofthe proper size for the presentation of one gure vat 'a time of the four rotary dials iiclrregisterjthe number of revolutions'cf the hand t, and each entirerevolution oi' hand t will measure one indred feet, superficial measurement.v rl .he metal point c projecting from the dial-plate B serves to mark the acc of beginning and ending the measurement. of a board or other piece of lumber.

To use my improved measuring instrument, the operator will irst `turnthe*eccentric'plate E around in the rection of the arrow in tig. 6,' to move the adjustable pinions 4, 5, 6, 7, 8, and 9 out of contact with transitting gear-wheel 2,. by pressing the thumb against the lever-12, (which lever works in a slot at the edge of m or drum In) when he'may adjust the revolving dials by turning around the hand f.` Byhis means the 0 on .ch ofthe rotary dials will be brought opposite to its respectiveopening u in vthe face owdial B, and the hand will be placed so as to point to the figures Mff The instrument 'being new adjusted to commence work, e operatoi.` will, by means of screw H, bririg that one of the series of adjustable `pinions 4, 5, 6, 7, 8, and i) mesh with transmitting wheel 2,-wliich will he indicated by the 1 gth ci' the lumber to be measured. In aginning'to measure across the lumber, the point c willbe placed directly over the edge of the lumber to easured, and theprotruding `portion of the wheel A, marked A,'will rest upon the faeeof the board or lumber; hen the operation of measuring (by, revolving thewheel A. across the material to be measured) will begin, and iring the rotation of the wheel A the thumb-spring m will bev-depressed to'relieve the wheel of brake'g; but ben the wheel-has traversed across the board or piece ol' lumber, and the pointe arrives directly over the lge, thethumblspring m will be released, which will permit the brake q to retain the wheel fromV further rotaon or change oi'gpcsition nntilrthe next operation of measuring begins, when the thumb-spring m must be v gain depressed to allowthc wheel A to revolve freely over .the surface being measured. The rotation of wheel drives the mechanism with which it is connected, and causes the registry'of its revolutions to be made by the ali-B and rotary dials R T I I. Wheel A communicates its movement'throughthe pinion :c in its hub to the ng spur-gear 3; thence throughpinion '11 .tothe cone/of pinions 4, 5,- 6, 7, 8, endg, thence through that one :".the series of the 'conve of piuions which may be in mesh with wheel 2 to the latter, which, being fixed upon s shaft,l causes it to revolve and actunvte the, small disk s, in the groove a' of which the arm a works.V The rotaons of disk s will cause the pointer t 4to move with it, the lat-ter being secured to the disk s' bythe screw u. *'t ill be observed that the connectijon of thc'gearing described above transmits' the movement of wheel ,as: it states immeasuring lumberfeef tile 'pointer-bami tand disk @and vthat the ;rotadbions` ofV dish` s, with its arm v, ivcs motion at regular intervals tov the four registeringdials, as hereinbefore described," The fucefof dial-*plate i has markedthereo'n assale, representing one Vhundred divisions, each representing one foot, superiicial meas rement, and when the hand t has made one entire rotation, beginningits circuiti'ati'cermit indicates that the` he'i has measured one hundreitfsnper'tieial feet, which numher'ivill be'registercdbyrotary dial ltr-which will'l resent the gnre l at 'the right-:hand llnileef in the dial-plate B; and when ten revolutions of hand t are aecomiished, ro t'ary dial R will present :at its:ripening in diai B zero, and at the same .time rotary dial 'l will presentV t its epeningin dialB the'gure .1, which '.will indieatethe measurement of one thousand i'e'ct; and by the likercceef'bperation all four ofthe rotary `,dials are broughntrinte action until one million feet are measured and ieufeantty recorded, as has beenk explained. The operation-:iis the sume, of recording' correllfylthe quantity 68,911 Il *J measured, whatever maybe the adjustment of the series of the six adjustable pinious 4, 5, G, 7, 8and 9. The` same principle of construe-tion may be readily carried to any necessary degree to eect the measurement, and registering oi' the quantity contained, when the articles measured are of di'erent lengths from those which can i be measiired by the machine as new organized. It should be observedthat the frame F, and screw II, for

adjusting the conc-shaped series of pinions,'nmy be dispensed with, and the yoke G, which embraces the adjustable pnions 4, 5, 6, 7, 8, and 9,' may be moved up and down upon the shaft l10- by `means of the projecting arm K; and the arm K may be made to extend-through an opening in drum L, which would be so formed and notched as to serve to perform the functions of the notched segmental plate N. Small curved slots'maybe'made through theI face of dial B, through which a. pin orother sharp instrlunentvmay be inserted,` `to set the rotary dials at-the beginning of each several measurement of different lots of lumber. In that case, the disks ordials B.' TQI( I would have small indentations formed around their faces, into which the point of the sh'arp instrument wold enter, to revolve them to set each at zero. V

Having fully described myfinvention, what I claim, and desire to secure by Letters Petent, is'

1. Registering the quantity of material measuredby a traversing rotarywheel, npon rotary andixed Vby an organization of mechanism substantially as described. Y

A 2. The combination of the shipping mechanism with an adjustable seriesb of di`erent-.sizedpinions' for changing speed, substantially as specified. l
